However, the Gunners were strangely subdued from the off at the Emirates and they were unlucky not to be behind early on when John McGinn had a goal disallowed following a VAR review.
But Villa quickly got a deserved opener when Bukayo Saka scored an own goal and Ollie Watkins scored twice in the second half to round off the victory.
It was Arsenal’s fourth defeat in eight matches and Arteta made no excuses for his side afterwards, claiming it was the first time under his management that they have failed to play as a ‘team’.
‘First of all congratulations to Aston Villa for the way they played and the victory,’ said Arteta.
‘After that obviously we perform below our standards and I have to say since I was Arsenal manager it was the first time I’ve seen us play and we were not a team.
‘I take full responsibility. We did not start the game well enough. We got away with the situation with VAR because of the offside situation but straight after that we lost all the races, all the duels, we were sloppy on the ball and when we created the chances to score we didn’t even hit the target.
‘It’s a really bad combination as the game went on we started to get more open and left more spaces, on the counter attack we looked very vulnerable.’
The Gunners take on Leeds United at Elland Road after the restart and the Spaniard will be hoping that Thomas Partey can shake off a thigh injury.
The Ghanaian was taken off at half-time against Villa as he was struggling in the dying stages of the first half with the issue.
